A new type of AC-DC-AC boost MC (boost matrix converter) based on boost circuit is presented, by connecting a boost circuit operating in the state of high frequency to the middle direct current link of AC-DC-AC matrix converter. The voltage transfer ratio of matrix converter is increased through utilizing the voltage increase function of boost circuit. In this paper, the mathematic model of boost...
This paper describes a three-phase AC/DC power converter involving a simple rectifier topology, which operates in PFC mode. This topology is close to another known, i.e. the VIENNA one. Two coils are involved in each phase. This permits to get a ldquoDouble Boost Effectrdquo and improves the rectifier features. The mains currents are under control of three analog self-oscillating controllers. Simulations...
In this paper a novel AC/DC rectifier topology is proposed. It operates in continuous current and PFC modes. This topology is close from the "VIENNA" one. By involving two coils, it permits to get a "Double Boost Effect", thus improves the rectifier features. Indeed, it exhibits the following advantages: (a) a Boost and a Buck-Boost effects operate and permit to transmit the energy...
The matrix rectifier described in this paper can realizes three-phase AC voltages to a DC output voltage and can work as a power factor correction converter. The paper presents an SPWM control strategy based on virtual DC link for AC/DC matrix rectifier with high frequency link. The matrix converter in the paper can be equivalent to a virtual rectifier and a virtual inverter. The proposed control...
